Semantic-TemporalNet: Refined Detection of Changes in Urban Blocks

Note: This project is under active development and will be continuously updated upon publication.

🔍 Project Overview

Semantic-TemporalNet is a deep learning framework designed to detect refined temporal changes in urban blocks using multi-temporal remote sensing imagery.

This project code is partially inspired by the architecture in pytorch-playground.

🧪 Example Inference

To evaluate semantic consistency scores of urban blocks, run the following command using the default parser settings:

python test.py --threshold 0.8

This will generate semantic coherence score visualizations for:

🏙️ Block 46 (Wuhan)

• Demo Output
  

• Visualization in Paper
  

🏙️ Block 1932 (Wuhan)

• Demo Output
  

• Visualization in Paper
  

These images illustrate the model's ability to detect and evaluate fine-grained temporal consistency across urban regions.
